In rare cases, theintraocular lens may not function properly or may move to a different position, and this means that the lens may need to be removed, exchanged or repositioned. If this happens, the cataract surgery recovery time may take longer than anticipated. Although these complications rarely occur in most patients, it should also be noted that significant loss of vision may occur. Thus, there is aneed for close follow-up after the surgery to ensure things work out as intended. If a patient has pre-existing floaters or muscular degeneration, contact surgery may not make these conditions better.
